This invention relates to expansible buckles and more particularly tobelt buckles.

With belts commonly used, the wearer adjusts the same to the shape ofhis waistline p when in an upright position. When bending or in asitting posture, the shape of a person becomes distorted and the abdomenenlarged and a belt adjusted for normal size will cause 3 p a bindingaction thereon.

'10' It is, therefore, one of the objects of the present invention toprovide a belt buckle,

which,when attached to a belt, will provide i resilient connectionbetween the ends thereof, and thereby compensate for variatlons 1n shapeof a wearer due to bending or slttlngt Other objects will appear in thecourse of the following specification and accompanying drawing in whichsimilar characters repre- .sent corresponding parts and in which:

Having reference to the particular embodi-' JIlGIlt'Of the inventionillustrated 1 indicates a buckle comprising a spring box 2, having abase 3 concavoconvexly shaped, perforated side walls e and end walls 5and 6. Arranged within the box 2 is an expansion spring 7, hav ing oneend 8 in abutment with the wall 5. Arranged over the spring 7 andbetween the walls 4 is a slide plate 9, having a depending lip 10 at oneend adapted to be inserted between the other end 11 of the spring 7 andthe wall 6. Formed at the other end ofthe plate 9 is an eye 12 to whichis pivotallycon nected a link 13 by the pin 14; Attached to the link 13by the clamping buttons 15, at one end 16 is a belt 17.
